Agricultural residues/by-products have become a popular choice for the manufacturing of building materials due to their cost-effectiveness and environmental friendliness, making them viable option achieving sustainability in construction sector. This study addresses utilisation two agro-wastes, i.e., eggshell walnut shell, manufacture unburnt clay blocks. The experiments were carried out on thr...

this article is devoted to the simultaneous optimization of shape and topology of shell structures. the optimum shape is obtained together with the optimum layout for the reinforcement layers at the both sides of the shell surface. to solve this problem the finite element method is employed. it is assumed that each element is comprised of a porous media with microscopic rectangular voids where ...

Crystal violet (CV) was removed from aqueous solutions using walnut shell (WS) as an adsorbent. The effect of initial ph, contact time, adsorbent level and temperature on CV adsorption, were studied in batch mode. The results indicated that both the Langmuir and the Freundlich equations effectively described the adsorption equilibrium. A pseudo second-order kinetics provided a perfect fit for t...

Lentinus edodes (L. edodes) is one of the most famous traditional Chinese medicines and high producer of various bioactive compounds such as polysaccharides. Modern pharmaceutical research shows that the Polysaccharides (LEPLS) of this mushroom is a kind of bioactive compound with clinical significance in medicine and several physiological effects. Up to now, fermentation system has been widely...

Simulation can be used to visualize the mechanical classification of walnuts. It collect microscopic information about walnuts in roller and guide its optimization design. In this process, simulation parameters are essential factors that ensure effectiveness simulation. study, crucial thin-skinned walnut particles were determined by combining discrete element method (DEM) physical tests. Firstl...

In the present work, the simultaneous determination of Brilliant green (BG) and Crystal violet (CV) dyes with overlapped absorption spectra in binary mixture solution, was carreid out using the partial least squares (PLS) and direct ortogonal signal correction-partial least squares (DOSC-PLS) methods. The results obtained indicate that by applying DOSC on the calibration and prediction data for...

This study investigated the effect of temperature, different concentrations of sodium carbonate,and the dose of organic solvent on the desorption of Reactive Red 198 dye from dye-saturated activated carbon using batch and continuous systems. The results of the batch desorption test showed 60% acetone in water as the optimum amount. However, when the concentration of sodium carbonate was raised,...

Mining waste dumps are present all over the world. One of main problems of these solid deposits is migration heavy metals in them due to the aqueous solutions flowing through them. The comparison removal of heavy from an solution a real mining leachate under different conditions by two different agricultural wastes has been investigated. effect pH, contact time and dosage was studied using...
